Abstract
We introduce a new concept of generalized metric spaces for which we extend some well-known fixed point results including Banach contraction principle, Cirics fixed point theorem, a fixed point result due to Ran and Reurings, and a fixed point result due to Nieto and Rodriguez-Lopez. This new concept of generalized metric spaces recover various topological spaces including standard metric spaces, b-metric spaces, dislocated metric spaces, and modular spaces.
